This is sometimes caused by running configure with one compiler and
doing the bootstrap with another.   Since you aren't very far into the
build at all, I suggest completely removing this build area and 
configuring and building with an explictit path to eliminate confusion.

	rm -fr your work area to eliminate config.cache and friends
	CC=/bin/cc .../path/to/configure
	make bootstrap


Alternately, simply get the installable binaries of GCC 2.95 that have
been exercised on UnixWare 7 from the caldera web site.
